Publication

2.1 How many

98,356 CVEs published in , 2.1 times as many as in .

91.0% carry an ID reserved the same year, so the rise is not a backlog of old IDs being published. Drag across the chart to choose dates.

GitHub_M added the most: +10,397 of the +51,231 change from to (20.3%).

The assigner is the organization that issued the ID, not necessarily the vendor of the affected product. 412 assigners published in 2026, against 363 in 2025. The Linux kernel's CVE team assigns an ID to “any bugfix that they identify”.6 Press × to leave an assigner out of every figure on the page.

Documented exploitation

Red = in KEV

KEV is the only exploitation evidence used here.2 A listing means exploitation was documented at least once, not how often or whether it continues.

  • An entry requires a CVE and a fix, so flaws missing either cannot be listed.
  • It leans toward large vendors: Microsoft accounts for 391 of 1,779 entries.
  • Entries are dated when CISA adds them, not when attacks began. Absence from KEV does not mean a flaw was never exploited.
3.1 Year by year

In Nov 2025 – Oct 2026: 98,356 CVEs published, 313 added to KEV. The 12 months before: 47,125 and 252.

The two rows use separate scales. Because KEV lags and undercounts, it cannot show whether exploitation kept pace with publication.

3.3 Time to listing

313 CVEs were added to KEV in : 130 within a week of publication, 54 more than a year after, 8 before it.

Listings keep arriving for years, so a recent cohort's share is not final. Time to listing is not time to first exploitation.

3.4 Same window, every quarter

Within of publication, 0.28% of Q1 2026's CVEs were in KEV, against 0.52% of Q1 2022's.

Each quarter is measured over the same 180 days after publication, so older CVEs' extra time doesn't count. Hatched quarters haven't had 180 days yet.

3.5 Severity, evidence, forecast

The same 48,150 CVEs from 2025: 77.7% have one CVSS score; 197 are in KEV, 22 rated Low or Medium; EPSS gives 752 a probability of or more.

Severity, documented exploitation and forecast answer different questions. EPSS is the 12 November 2026 forecast for the next 30 days4; a missing score is unknown, never zero.

What this cannot tell you

  • Breaches that start another way. Exploitation was the top initial access vector in Verizon's 2026 data, at 31% of breaches with a known vector; most began otherwise.7
  • Flaws without a CVE: in-house code, silent hosted-service fixes, anything undisclosed.
  • Exploitation outside KEV.
  • Why publication is rising. More discovery, more reporting and more assigners look the same in this data.
  • Severity trends. NVD scored 82.7% of 2020 CVEs and 8.2% of 2026's.3
  • Victims, losses, or whether we are more secure.
